The Bluetooth Special Interest Group is going to update its roadmap out to Q3 2007, focusing on interoperability with UWB media-access control layers, enhanced security features, advanced topologies and better quality of the service.
The first core release, codenamed Lisbon, is essentially complete and covers the Enhanced Data Rate 2.0 version. This will be released early next year, and according to Mike Foley, Bluetooth SIG executive director, prototyping of devices that meet the specifications should be completed by the second quarter of 2006.
The next core, dubbed Seattle, will be the first to feature the specifications coming down from the agreement with the ultrawideband community that will make Bluetooth technology compatible with UWB.
